Every single fresh water body of water around here has mullet in it. Tarpon, snook, reds often too. Even Jacks, sheephead and ladyfish if your close enough to the coast for saltwater intrusion. I'm a couple towns south of you. Often times over the last 50 years developers and county governments have rerouted drainage's. The mosquito control ditches of the '40's and '50's are often filled in from lack of maintenance or were filled in so developers could make $ off every inch of land. Very few times flood tides from storms like the 'NoName" storm in '93 caused plenty of immigrated fish. I know guys who purposely transfer big snook into ponds for their own private enjoyment. Just remember to keep some mullet colored lures on hand because the bass tarpon and snook will feed heavily on the baby mullet since the bream have been pushed out by the tilapia and are not populated enough to be a viable forage base.
